Bolivia bus plunges off road, killing dozens

A public bus careered off a winding road and plunged some 100 metres into a ravine in southern Bolivia, near the Argentine border, killing at least 28 people and leaving 10 injured, officials said.

An investigation has been launched into the crash, said transport officials in the city of Tarija, 919 kilometres from the capital, but initial findings were that poor visibility and speed was a major factor in the accident.

The bus, reportedly carrying some 70 passengers - well over the legal limit - was en route from the border town of Villazon to Tarija, when it came off the road at steep section of the road known as Cuesta de Sama.

Bolivian roads are some of the most notorious in Latin America, with 1,000 deaths and 40,000 injuries each year, according to official figures published in 2010.
